The Use of In Vitro Techniques in Groundnut Improvement uri icon

abstract

  • Genetic improvement of crops by utilization of characters fromwild species, which often have desirable traits not present in thecultivated forms, has been the subject of serious attention. Theinterspecific transfer of genes has not always been simple andstraightforward because of reproductive barriers and genetic incompatibility.This is true in the genus Arachis where a number ofspecies have been identified as sources of resistance to fungal andviral pathogens as well as to insect pests (1 1. A few species havebeen crossed with A. hypogaea and their derivatives produced (1 -41, but there are 'l; number of species which are not crossable withoundnut (5). This limits the scope for crop improvement, and thesS. tuation necessitates the adoption of existing methods, or develop- ment of new ones for the production of hybrids following these desirklewide crosses
